No, my mistake, that's rubbish ... on a 64bit processor the fieldds only occupy 
28 bytes, so the 32 byte offset is produced by alignment rules rounding up to a 
16byte boundery.
In that case, the offsets calculated by the compiler would be consistent with 
it ignoring the two __unsafe_unretained pointers.  Perhaps that is a clue?
